there is no such thing as unskilled labour
This post made me realise something important – you have never just become good at your job. You have become skilled. You have gained skills. If you can do something quickly and correctly, without supervision, you are highly skilled. If you don’t have to think about doing something while doing it, it had become a motor skill for you – you are highly skilled. If you comprehend jargon used on the job, if you know measurements or filling or abbreviations or situations that only occur in a workplace – you are skilled and knowledgeable.
